TL;DR: In this article, the authors present a mixed method analysis of the needs and motivations of the delegates of academic, scientific and professional (ASP) conferences, finding that delegates are divided as to the longterm worth and benefit of conferences, particularly when they consider how their activities and contributions were viewed and appreciated by others.
Abstract: Conferences are generally felt to facilitate knowledge exchange and interactions between delegates, and to support formative higher education and continued professional education. However, the motivations and needs of conference delegates are sparsely researched and subjective in nature. This paper presents a mixed method analysis of the needs and motivations of the delegates of academic, scientific and professional (ASP) conferences. A series of 16 mixed method expert interviews were conducted with a randomly selected international sample of established academic faculty. The results were cross-referenced with the findings of a preceding pilot survey (n=37) that included student as well as established researchers. When examined together, the research shows that whilst ASP delegate needs and expectations seem to be met on a superficial level, delegates are divided as to the long-term worth and benefit of conferences, particularly when they consider how their activities and contributions were viewed and appreciated by others. Although the empirical findings are representative of the participants’ perceptions of conferences, they offer an advancement on the opinion-based literature on conference motivations. Importantly, this research helps to explain why delegates hold mixed perceptions of conferences, and identifies key areas where added value is needed to meet contemporary delegate need.

TL;DR: In this paper, the amount of nutrients (N and P) and trace elements (Cd and Pb) accumulated and incorporated into the snow and sea ice cover was assessed for the northern Baltic Sea, resulting in an estimate for the potential flux of nutrients and trace element to underlying waters during sea ice and snow melt.
Abstract: The amount of nutrients (N and P) and trace elements (Cd and Pb) accumulated and incorporated into the snow and sea ice cover was assessed for the northern Baltic Sea, resulting in an estimate for the potential flux of nutrients and trace elements to underlying waters during sea ice and snow melt. From the atmosphere the sea ice and snow cover accumulate less than 3% of the annual N and P load, and about 5% of the annual Cd and Pb load to the Bothnian Bay. The atmospheric deposition of nutrients to the northern Baltic Sea has declined considerably during the last decade. The total accumulation in the snow and ice, from the atmosphere and seawater, make up to 6% of the annual nutrient and up to 40% of the annual Cd and Pb load into the Bothnian Bay. Thus sea ice plays an important, but still poorly understood role inchemical cycling, transformations, and budgets. The fate of substances accumulated and released from snow and sea ice merit further investigation, especially if sea ice is a source and a platform for transformation of accumulated substances, thus indirectly affecting their toxicity and/or bioavailability before they are released to the water column.

TL;DR: The authors investigates the kinds of environmental agencies that are constructed for, and by, indigenous peoples within the United Nations (UN) Permanent Forum on Indigenous Issues (PF) and the Arctic Council.
Abstract: Indigenous peoples are often perceived as custodians of nature owing to their close relationship with their environment and their nature-based livelihoods. This paper investigates the kinds of environmental agencies that are constructed for, and by, indigenous peoples within the United Nations (UN) Permanent Forum on Indigenous Issues (PF) and the Arctic Council. The particular focus of this research is the issue of responsibility. The article brings together empirical materials from the two forums and engages with them using Foucault-inspired approaches. We offer a critical discussion of indigenous peoples' environmental agency in international politics, addressing the need to problematize representations of indigenous agency that to date have been largely unchallenged in both the practice and study of international politics. We identify three perspectives through which the environmental agency of indigenous peoples is validated and justified: having particular knowledge, being stakeholders, and having a close relationship with nature. Certain kinds of expectations are inscribed in each of these perspectives; responsibility becomes intertwined with agency.

TL;DR: In this paper, the authors analyzed the tree rings of pines in two tree classes (living and dead) from an urban park in Helsinki to reveal their growth variations and to examine the obtained chronologies along with climatic data.
Abstract: The mortality of Scots pine trees in and around Helsinki has been reported in recent years, but the causalities of these deaths have not so far been rigorously examined. Tree-ring analyses have previously shown to effectively reveal historical growth variability and thus hint at the stress factors behind tree mortality. Here, we analyzed the tree rings of pines in two tree classes (living and dead) from an urban park in Helsinki to reveal their growth variations and to examine the obtained chronologies along with climatic data. Guided by tree-ring information, the pine growth over the past century could be divided into four episodes: average growth conditions during the first half of the twentieth century, a suppressed growth period during the 1950s and 1960s, a growth release since the mid-1970s, and a period of recent mortality. The two tree classes became particularly differentiated during the release period in that the growth of surviving pines underwent a more positive and abrupt growth anomaly in comparison to dead pines. The survival of pines could also be linked to their sensitivity to droughts in a long-term context: The growth of still-living pines showed a statistically significant moisture sensitivity over the second half of the century only. The period 2002–2003 (coinciding with drought) was observed as a dendrochronologically dated episode with a 40% mortality. Overall, the results point to the importance of tree competitive strength and climate as predisposing and inciting/contributing factors behind the tree mortality.

TL;DR: In this article, the authors add a continuousuum damage model to the BISICLES model to model the localized opening of crevasses under stress, the transport of those crevass through the ice sheet, and the coupling between crevasse depth and the ice flow field and carry out idealized numerical experiments examining the broad impact on large-scale ice sheet and shelf dynamics.
Abstract: . Floating ice shelves exert a stabilizing force onto the inland ice sheet. However, this buttressing effect is diminished by the fracture process, which on large scales effectively softens the ice, accelerating its flow, increasing calving, and potentially leading to ice shelf breakup. We add a continuum damage model (CDM) to the BISICLES ice sheet model, which is intended to model the localized opening of crevasses under stress, the transport of those crevasses through the ice sheet, and the coupling between crevasse depth and the ice flow field and to carry out idealized numerical experiments examining the broad impact on large-scale ice sheet and shelf dynamics. In each case we see a complex pattern of damage evolve over time, with an eventual loss of buttressing approximately equivalent to halving the thickness of the ice shelf. We find that it is possible to achieve a similar ice flow pattern using a simple rule of thumb: introducing an enhancement factor ∼ 10 everywhere in the model domain. However, spatially varying damage (or equivalently, enhancement factor) fields set at the start of prognostic calculations to match velocity observations, as is widely done in ice sheet simulations, ought to evolve in time, or grounding line retreat can be slowed by an order of magnitude.
